It said: "We are shocked and saddened at the news of Dolores’s passing, mere hours before she was to record vocals on our upcoming version of Zombie.

"We have always had deep respect for her as an artist and a vocalist and she was never afraid to bare her soul in her music and lyrics.

"Zombie is an incredibly personal song and although we are a hard rock band, we always felt the rawness and honesty she projected on stage and in her recordings was something to which all bands should aspire to, regardless of genre.

"When we heard she liked our version and wanted to sing on it, it was the greatest compliment a new band, or any band for that matter, could have received.
